INSTALLATION TECHNOLOGY
–
STRUCTURES THICKER THAN 125 mm
In rigid walls, with thickness less than or equal to 125 mm, WKP-P fire dampers are installed in this way that an axis
of the fire baffle matches the axis of the wall, and ensure a concentricity of fire damper and installation opening.
In case when wall have more than 125 mm thickness: WKP-P fire dampers are installed in this way that the damper
border is flush with the wall surface (Fig. 6).

INSTALLATION TECHNOLOGY
–
FLEXIBLE WALL WITH 125 mm THICKNESS
a.
Make an opening in the wall with the dimensions 310 mm greater than the width B and 180 mm greater than
the heigh H: this is B+310 and H+180.
b.
For the dampers which have height H=200 mm and H=300 mm installation opening should have height H+160
[mm] (acceptable
140÷180 [mm]).
c.
Make a frame of two layers of GKF boards 15 mm thick and a width corresponding to the installation opening
screwed tightly, bearing in mind the exact sealing at their joints by using Hilti Firestop Coating CP 673,
Promastop-Coating, Promaseal-Mastic or Soudal Firesilicone B1 FR.
d.
Put the closed fire damper into the installation opening and support or suspend, in this way that an axis of the
fire baffle matches the axis of the wall, and ensure a concentricity of fire damper and installation opening.
e.
After setting the fire damper as described, fill the gap between the fire damper and the wall with non-flammable
mineral wool of high density, 100 kg/m3 or more.
f.
Seal the place of filling with mineral wool using the sealing mass given in pts.2
g.
Mount the collar, of GKF boards on both side of wall, with a thickness of 15 mm and a width of 150 mm, with
the screws.
h.
After mounting the collar, remove the supports or suspensions, check the fire damper correct operation and
leave it in open position.
